Abstract

An automatic loading disc player comprising a detection system for preventing mistaken insertion of a compact disc which is smaller than the conventional disc. The disc player comprises conveying rollers (4a,4b) for conveying the disc to a disc playing position and returning the disc to a disc insertion position. The disc player further comprises a first detection means (52) provided near the conveying rollers for detecting the presence or absence of a data recording disc, a second means for detecting (10) when a data recording disc is loaded at the disc playing position, and a control means (6) for controlling the driving of the conveying rollers in the forward or reverse direction, the control means operating to stop the driving of the conveying rollers in the forward direction when, in loading a data recording disc, the detection of the presence of the disc by the first detecting means is interrupted before the second detecting means detects the completion of loading of the disc.
